A 79-year-old Caucasian man presented with multiple leg abscesses due to Nocardia pseudobrasiliensis. He was on chronic steroid therapy for myasthenia gravis. We present the difficulties in diagnosis and treatment of this rare organism. N. pseudobrasiliensis is a new emerging species that was previously thought to belong to the N. brasiliensis species. The distinction between the two species is extremely important given the different antibiotic susceptibility pattern and association of N. pseudobrasiliensis with more invasive and disseminated disease.
一名79岁的白种男性因伪巴西奴卡菌感染出现多处腿部脓肿。他因重症肌无力正在接受慢性类固醇治疗。我们展示了这种罕见病原体诊断和治疗中的困难。伪巴西奴卡菌是一个新出现的菌种,以前被认为属于巴西奴卡菌菌种。鉴于这两个菌种不同的抗生素敏感性模式以及伪巴西奴卡菌与更具侵袭性和播散性疾病的关联,区分这两个菌种极为重要。
